Abstract:

Abstract This article discusses the creation of a 3D archive and physical copies of paper reliefs (estamages). A matrix of the estampage is fabricated by the combined use of 3D scanning technology and additive technologies which can then be used for the documentation and conservation of the original estampage. In order to digitize the relief, an optical 3D scanner based on structured light was used and the processing of the 3D model is discussed in detail. Scanning data is uploaded into the microprocessor of a 3D laser printer using stereolithography technology which then creates a conservatio

Abstract:

In the article we describe the methods for construction of underwater 3D relief (bathymetry) and combining it with the corresponding ground relief (terrain) when the bathymetry information is of much lower quality than that of terrain. We have developed an algorithm for combining the low quality underwater relief with the higher quality ground relief using Delaunay triangulations. The resulting combined 3D model of relief has no noticeable artifacts and can be used to solve various hydrological tasks, such as computation of the HPP reservoir water level in dependence to the water discharges of

Abstract:

It is challenging to extract reliefs from ancient steles due to their rough surfaces which contain relief-like noise such as dents and scratches. In this paper, we propose a method to segment relief region from 3D scanned ancient stele by exploiting local surface characteristics. For each surface point, four points that are apart from the reference point along the direction of the principal curvatures of the point are identified. The spin images of the reference point and the four relative points are concatenated to provide additional local surface information of the reference point. A random

Abstract:

The authors propose an algorithm for predictive monitoring of 3D-changes in the terrain relief due to the processes of slope erosion. The algorithm is based on the phenomenological law, from which it follows that the intensity of soil losses at the slope is proportional in magnitude and inverse in the direction of the declivity height gradient vector. In conjunction with the differential equation of mass balance, a mathematical model of the terrain relief change is built. The model enables calculating it at an arbitrary time according to its shape at the initial moment based on the solution of

Abstract:

We present a 3D gravity inversion technique, based on the Marquardt algorithm, to analyze gravity anomalies attributable to basement interfaces above which the density contrast varies continuously with depth. The salient feature of this inversion is that the initial depth of the basement is not a required input. The proposed inversion simultaneously estimates the depth of the basement interface and the regional gravity background. Applicability and efficacy of the inversion is demonstrated with a synthetic model of a density interface. We analyze the synthetic gravity anomalies (1) solely beca

Abstract:

Relevance and purpose of the work. Due to its basement fault block pattern in the sedimentary basin, the Southwestern Gulf of Suez’s Gebel El-Zeit basin is one of Egypt’s most desirable hydrocarbon concessions. However, salt diapers in sedimentary layers have hindered seismic interpretations in this area, making it challenging to build a 3D central primary basinal structure. This study uses Bouguer gravity anomalies to input basement complex lateral density model assumptions to determine the optimal three-dimensional basement depth for the study area.

Abstract:

For the compression compartment safety design in gas filling station, hazards of gas explosion inside compression compartment should be assessed, and explosion energy as well as influence factors should be determined. In this paper, numerical simulation was adopted to build 3D model of compression compartment and simulate gas explosion pressure and flame propagation behavior under different ignition point location, open-pressure and weight of relief panels. The results show that the ignition point location relative to the location of the vent opening and relief panel’s characteristics is very

Abstract:

The surface of most heritage objects holds important clues about their creation. To answer specific research questions about the creation of a mural painting located in the Bishop's Gate porch of St. Stephen's Cathedral in Vienna, the three-dimensional geometry of the entire painted surface was digitised in minuscule detail using thousands of overlapping photographs. After a brief introduction to the basics of image-based surface digitisation, this paper describes in detail how the photographs were taken and how they were processed to create a digital three-dimensional surface.

Abstract:

Abstract Acoustics present an alternative sampling strategy in areas characterized by steep slopes and rugged terrain where fishing is impractical. However, when the interference between echoes from fish targets and boundaries is severe, acoustic observations require careful interpretation of the echo returns. This article outlines a method of generating a representative 3D model of the bottom topography that can assist in near-boundary fish discrimination. Images provide greater insight to echo source and highlight some of the difficulties associated with classifying acoustic sign. The result

There are many ways to add volume to still and moving images. Accordingly, technologies for creating three-dimensional graphics are extremely diverse in nature, allowing you to model virtual objects and create images based on them.

Abstract:

Change detection on the basis of multi-temporal imagery may lead to false alarms when the image has changed, whereas the scene has not. Geometric image differerences in an unchanged scene may be due to relief displacement, caused by diferent camera positions. Radiometric differences may be caused by changes in illumimation and shadow between the images, caused by a different position of the sun. The effects may be predicted, and after that compensated, if a 3d model of the scene is available. The paper presents an integrated approach to prediction of and compensation for relief displacement, s

The wave hydrodynamics model is applied to large reservoir of the valley type, such as Tsimlyansky reservoir.

In addition, they are modifiable only to a small extent and do not provide such accuracy as traditional maps.

An empirical thickness versus time relationship sand curve has been established in the Rub’ al-Khali desert and verified by a theoretical curve from the direct measurements of sand. The empirical sand curve has variable success in other areas of Saudi Arabia. We established a theoretical sand curve model to determine the single-way time in dry sand. Tomographic modeling of a higher resolution 3D seismic survey contributes more data to refine the relationship. Polynomial curves were used in the calculation of near-surface static corrections to improve the solution for low-relief structures.

Most object detection, recognition, and classification are performed using optical imagery. Images are unable to fully represent the real-world due to the limited range of the visible light spectrum reflected light from the surfaces of the objects. In this regard, physical and geometrical information from other data sources would compensate for the limitation of the optical imagery and bring a synergistic effect for training deep learning (DL) models.

This study established a novel descriptive method based on a digital elevation model to describe the difference between intervalley plains and intermountain flats.
